I am growing this cool and moderately bright. It has been on this hardwood mount since April 2008 and will need to be remounted pretty soon. It also needs a bath of H2O2 to get rid of the algae on the leaves to look its best. There is a very thin layer of naturally occurring (and unwelcome) moss. There was no moss on the mount when I put it on. The plant dries most days between waterings. Next time I'll try to put it on a longer mount so the roots have a bit of room to run.
